python datetime fromtimestamp yielding valueerror year out of range -

this question has answer here:

• javascript timestamp python datetime conversion 3 answers

when attempting convert float formatted timestamp e.g 1437506779950.0 datetime object, i'm getting valueerror "year out of range".

this code used, working not 3 months ago. revisiting now, strangely throwing error yet nothing in code base has changed, data being passed it, , data has changed there timestamp.

>>> f = 1437506779950.0 >>> datetime.datetime.fromtimestamp(float(f)) traceback (most recent call last):   file "<stdin>", line 1, in <module> valueerror: year out of range 

i can't understand have changed make break?

as noted in answer this question, looks unit conversion issue. have divide timestamp 1000 convert milliseconds seconds.
